In this VIS image, taken by the NASA - Mars Odyssey Orbiter on November, 14th, 2013, and during its 52.872nd orbit around the Red Planet, we can see several Fractures, Collapse Features (---> Channels and a Pits' Chains - the biggest one, is visible toward the right (Dx) lower side of the frame) and ancient Lava Flows, which are all located on the Northern Flank of the huge Shield Volcano known as Ascraeus Mons. Just out of curiosity, no Impact Craters seem to be present in this specific area of the Volcano (as a matter of fact, all the round Surface Features that can be seen here are, in our opinion, as IPF, shallow Collapse Pits - including the very small one located exactly on the lower right (Dx) corner of the frame).

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 17823) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
